AIM:To observe the clinical effects of the small incision non phacoemusification cataract surgery in 462 Sudanese cataract cases(536 eyes).

METHODS:From September 2013 to August 2015, we analyzed the 462 Sudanese cataract cases(536 eyes)performed cataract surgery by the way of the small incision non phacoemusification with intraocular lens(IOL)implantation and summarized the intraoperative and postoperative complications, the eyesight and intraocular pressure(IOP)of the eyes in 1d, 1wk and 1mo after operation.

RESULTS: Intraoperative complications: posterior capsular ruptured and vitreous prolapsed in 18 eyes(3.4%), iris prolapsed in 10 eyes(1.9%), suspensory ligament of the lens ruptured in 7 eyes(1.3%), not implanted IOL in 5 eyes(0.9%), descent's membrane detachment in 3 eyes(0.6%), iridodialysis in 1 eye(0.2%). Postoperative complications: corneal edema in 47 eyes(8.8%), anterior chamber inflammatory reaction in 32 eyes(6.0%), pupil oval or slightly upward in 12 eyes(2.2%), the upper iris incarcerated in the tunnel incision in 3 eyes(0.6%),hyphema in 2 eyes(0.4%), infective endophthalmitis in 1 eye(0.2%). Visual acuity: uncorrected visual acuity were ≤0.1 in 52 eyes(9.7%), >0.1-<0.3 in 97 eyes(18.1%), 0.3-<0.5 in 129 eyes(24.1%), and ≥0.5 in 258 eyes(48.1%)in 1d after operation. Uncorrected visual acuity was ≤0.1 in 28 eyes(5.2%), >0.1-<0.3 in 66 eyes(12.3%), 0.3-<0.5 in 150 eyes(28.0%), and ≥0.5 in 292 eyes(54.5%)in 1wk after operation. At 1mo after operation, some patients did not follow-up on time, uncorrected visual acuity of reviewer above 0.5 in 321 eyes. IOP: in 1d after operation, IOP above 20 mmHg in 26 eyes(4.9%). In 1wk after operation, IOP above 20 mmHg in 2 eyes(0.4%). In 1mo after operation, 1 eye was still poor control with traumatic cataract surgery, and IOP returned to normal after the reoperation of trabeculectomy.

CONCLUSION:The small incision non phacoemusification cataract surgery with IOL implantation has the advantages of small incision, short operation time, relatively safe, easy to mastered, no-suture, quick visual function recovery and low cost. And, the operation equipments are simple and do not need many expensive medical equipments, supplies and professional staffs. So, the small incision non phacoemusification cataract surgery with IOL implantation is suitable for the anti-blind work of cataract in the foreign aid and remote areas.
